The sink entrance to Bo’s Cave is 24’ wide x 11’ across, elevation 1055’.  Descend 11’ down the sloped sink to a horizontal entrance 8’ wide and 2.5’ high below an exposed Monteagle Rock shelf.  Just inside the horizontal entrance, passage continues both up and downstream².  The passage dimensions here are 14’ wide by 6’ high.  Going downstream, the walls quickly narrow.  My objective was to keep my boots from getting totally soaked so I chimneyed above the pooled passage floor for 25’ until the narrow canyon opens 19’ wide and 6’ high to the left. 

A slope on the left wall ascends to a dry upper level where a belly crawl begins and quickly ends after 8’ to the left and to the right the upper level crawl reconnects 40’ further downstream in the main passage.  The passage is now 18’ wide and walking passage continues for 200-300’ and the passage ceiling heightens creating a 15’ high by 13’ wide canyon with an additional 5’ of undercut rock on the right side. 

Just past the canyon passage, ceiling height lowers into a 90’ crawl with has only one brief standing interval before opening into walking canyon again.  Looking behind, you see that flowstone filled much of the upper canyon creating the crawlway.  The passage ahead narrows to 4’ wide but the ceiling increases to ~24’ high before lowering into a standing room which filters into another crawlway. 

Here you can go low to the right and get wet or high to the left and belly crawl over flowstone.  Another room is encountered after 45’ of crawling.  Then crawl into a crawling / stoop room and to the right you can crawl ahead and see the ceiling drop toward wet stream belly crawl. 

² Back at E1, after 25’ traveling upstream you encounter a passage split³.  Going left, a dry crawl continues for 20’ and then becomes a wet crawl for another 20’.  After 60’ feet of crawling, the passage splits again.  The left split is low and wet.  The right splits enters a dry belly crawl. 

³ Back at the first split, crawl ahead for 25’ where the ceiling lowers then opens slightly into a crawling room.  In 12’ more the passage splits.  A 12’ crawl to the right brings leads toward E2 ⁴.  An 8’ climbup to the left leads to 10’ of horizontal chimneying and then turns into a low, dry belly crawl. 

⁴ Heading toward E2, a brief formation squeeze opens and walks you 10’ into the bottom of the E2 sinkhole which is 20’ wide x 10’ across, elevation 1078.  Next to E2 is an adjacent sinkhole with what looks like a belly crawl under a rock ledge.
